The topic of quantum fluctuations in quasi-1D superconductors, also called quantum phase slips (QPS), has
attracted a significant attention. It has been shown that the phenomenon is capable to suppress zero resistivity of
ultra-narrow superconducting nanowires at low temperatures T<<Tc and quench persistent currents in tiny
nanorings. It has been predicted that a superconducting nanowire in the regime ...

Важной проблемой является обеспечение долговечности и стабильности работы светодиодов в условиях влияния радиационного излучения. Светодиоды, излучающие в сине-зеленой области спектра изготавливаются на основе многослойных эпитаксиальных гетероструктур твердых растворов, в качестве которого выбран GaN. В качестве подкладки таких светодиодов использован материал лейкосапфир – Al2O3.
Прототип разработанного светодиода имеет суммарное сопротивление на подложке 50,3 С/Вт, при номинальном токе 40 ...

Transhumanism is the brand-new term, which appears only in the beginning of the 21st century. The adherents of this term consider further development of humanity in a close contact with nanotechnology. People were always interested in how to improve the quality of life and prolong it. Medieval alchemists didn’t find the philosopher’s stone, the Holy ...

It is shown that copper films with copper nanowires located on them demonstrate enhancement of the catalytic effect during copper-oxide oxidation. Nanowires of different types (cylindrical and conical ones and arrays between two surfaces) are compared. It is revealed that the largest effect (an increase in the degree of oxidation by 60–70%) is achieved in ...

Graphene has been considered as one of the best materials to implement mechanical
resonators due to their excellent properties such as low mass, high quality factors and tunable
resonant frequencies. Here we report the observation of phonon lasing induced by the photonthermal

Quantum fluctuations in quasi-one-dimensional superconducting channels leading to spontaneous
changes of the phase of the order parameter by 2, alternatively called quantum phase slips (QPS),
manifest themselves as the finite resistance well below the critical temperature of thin superconducting
nanowires and the suppression of persistent currents in tiny superconducting nanorings. Here we report the
experimental evidence that in a ...

Ni and Fe metal nanowires of different lengths are synthesized in nanoporous matrices of polyethylene terephthalate track membranes. As samples dry, point agglomeration of the ends of the nanowires is observed at lengths corresponding to theoretical estimates. Point contact of nanowires can be used in surface-enhanced Raman scattering (SERS). ...

The smaller the system, typically - the higher is the impact of fluctuations. In narrow superconducting wires
sufficiently close to the critical temperature Tc thermal fluctuations are responsible for the experimentally
observable finite resistance. Quite recently it became possible to fabricate sub-10 nm superconducting
structures, where the finite resistivity was reported within the whole range of experimentally obtainable
temperatures. ...

Electron transport properties of titanium nanowires were experimentally studied. Below the effective diameter
50nm all samples demonstrated a pronounced broadening of the R(T ) dependencies, which cannot be accounted
for by thermal fluctuations. Extensive microscopic and elemental analyses indicate the absence of structural or/and
geometrical imperfections capable of broadening the R(T ) transition to such an extent. We ...

Существование однослойных нанотрубок, не нагруженных внутренним давлением, свидетельствует о необходимости учета моментного взаимодействия между атомами. В противном случае, слой атомов, формирующий нанотрубку, не имел бы изгибной жесткости, а стало быть, однослойная нанотрубка была бы неустойчива.
